LAMP-CHIMNEY HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 737,628, datedSeptember 1, 1903. Application filed May 11, 1903. Serial No. 156,515.(No model.)

To all whom it may concern.-

Be it known that I, EDWIN HOLMES, a subject of the King of GreatBritain, residing at Canning, county of Kings, Province of Nova Scotia,Canada, have invented certain new and useful Improvements inLamp-Chimney Holders; and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Myinvention relates to lamp-chimney holders; and my object is to providea simple device of this kind with an improved arrangement of the springsfor retaining the chimney at its base.

One of the objects of the invention is to ar range the holding-springsso that they will apply a pressure upon the chimney-base, which pressureis distributed over a certain appreciable area, in this way increasingthe holding force of the springs and lessening the liability of breakingthe chimney.

The invention consists in the construction and combination of parts, tobe more fully described hereinafter and definitely set forth in theclaims.

In the drawings, which fully illustrate my invention, Figure 1represents in perspective a burner to which my holderhas been applied.Fig. 2 represents this burner substantially in side elevation, a portionof the holding-springs being shown in section, as well as the lowerportion of the lamp-chimney, which is shown in position upon the burner.Fig. 3 is a perspective showing a portion of the burner and illustratinga modified form which my holder may take. Fig. 4 is also a perspectiveshowing a portion of the burner and a second modified form which myholder may take.

Throughout the drawings and specification the same numerals of referenceindicate like parts.

Referring more particularly to the parts, a represents a burner having abody 2 and l threaded nipple 3, said burner including a peripherallydisposed flange or base 4. Around the periphery of the burner there aredisposed a pluralityvof springs or holders 5. These springs arepreferably of the form shown in Figs. 1 and 2. It should appear to breakthe same.

that these springs comprise bows 6, which are disposed outwardly andwhich are formed below into curves or crooks 7, which crooks attach attheir extremities in any suitable manner beneath the aforesaid base 4.As indicated, the upper extremities of these springs are formed intooutwardly-bent tips or ears 8, to which tips are attached leaf-springsor clips 9. The lower portions 10 of these clips are substantiallystraight, as indicated, there being a slight bend or knuckle 11 above,beyond which bend they attach to the aforesaid ears 8. When thelamp'chimney is removed from the holder, the clips 9 normally occupy theposition in which they are shown in Fig. 1, where it should appear thattheir lower extremities rest against the periphery of the bowl 12 of theaforesaid burner-body. WVhen the lamp-chimney 13 is applied, its

base 14 is adapted to pass into the space between the clips orleaf-springs 9 in the manner indicated in Fig. 2, and it should appearthat the arrangement is such that when the lamp-chimney is applied inthe manner indicated the straight portions 10 of the aforesaid clipswill lie substantially flat against the sides of the base in the mannerillustrated. It will be observed that these clips 9 are so long thatthey almost touch the base 4 at their lower extremities. It should beunderstood that the resiliency of the clips or leafsprings 9 is notdepended upon solely to produce the holding pressure, as the aforesaidbows 6 also have animportant function in this respect. It should beobserved that the peculiar arrangement of the bows and clips tends toenhance the pliable or adaptable character of the holder. The form ofthe clips or leaf-springs themselves is especially adapted for giving afirm but resilient grasp upon the chimney-base, it being observed thatthe bend 11 aforesaid has its convex side toward the chimney-base, sothat the outward deflection of the lower portions of the clips will tendto increase the force which they exert without at the same time tendingIt should be stated that the outwardly-bent tips or ears 8 facilitatevery much the application of the lamp-chimney, and it should be evidentthat when the holders 5 are in the position in which they are shown inFig. 1 when ready to receive the chimney the fact that the lowerextremities of the clips rest against the side of the burner operates tomaintain the springs in a more open position to receive the chimney,

it being understood that the resiliency of the inner springs 9 ofiers aresistance to the resiliency of the bows 6, so that the bows would notbe permitted to move the ears 8 inwardly to as great an extent as wouldotherwise be the case. In this manner the springs which constitute theholder oppose each other, as it were, when they are not grasping thechimney and assist each other when they are grasping the chimney.

In Fig. 3 a modified form of the holder is shown. In this form it shouldappear that the clips 15 are formed integrally with the bows 16, thesaid bows being of substantial width and having an opening 17 formed inthe same, the position of which was occupied by the part 15 before itsformation. This form comprises an outwardly-bent ear 18, as before.

The form shown in Fig. 4 comprises an outer member or bow 19, which isintegral with the tongue 20, the said members being formed together intoan ear 21 at the upper edge 22, at which point they connect. The mode ofoperation of the forms shown in Figs. 3 and 4 is substantially the sameas that shown in Figs. 1 and 2, it appearing that the lower extremitiesof the members 15 and 20 rest against the periphery of the base in thesame manner as before.

The value of the construction described may be said to lie chiefly inthe advantageous manner of applying the spring force or pressure to thechimney over a considerable area and also in that feature of theconstruction by virtue of which the two resilient portions of thesprings or holders are made to oppose each other when the chimney isremoved, in this way operating to maintain the springs in a more openposition and in a position which could not otherwise be attained by theuse of an ordinary spring adapted to give an equivalent holding effect.

While I have shown in the accompanying drawings the preferred form of myinvention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orpost tion without affecting the operativeness or utility of myinvention, and I therefore reserve the right to make all suchmodifications as are included within the scope of the following claimsor of mechanical equivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a lamp-chimney holder, in combination, a base, a plurality ofresilient members disposed about said base, and adapted to receive thelower portion of a chimney therebetween, said resilient memberscomprising an outwardly-bowed portion, an inwardly-inclined portionconstituting an extension of said bowed portion, said inclined portionhaving an outwardly-inclined tip, and a leafspring constituting aportion of said tip, and

normally projecting inwardly and downwardly therebelow, said leaf-springbeing adapted to lie substantially flat against the outer side of saidlower portion of said chimney whereby the lower edge of said chimney mayrest upon said base.

2. In a lamp-chimney holder, in combination, a base, a plurality ofresilient members disposed about said base, and adapted to receive thelower portion of a chimney therebetween, said resilient members eachcomprising an outer resilient bowed member having a substantiallystraight inwardly-inclined upper extension, said extension having anoutwardly-turned ear, a leaf-spring constituting a portion of said earand projecting inwardly and downwardly therefrom, said leaf-springhaving a curve adjacent to the lower portion of said ear, the extremityof said ear normally resting against a portion of said base, the body ofsaid leaf-spring being adapted to dispose itself substantially flatlyupon the outer side of said lower portion of said chimney, whereby thelower edge of said chimney may rest upon said base.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
